The United States of America is the leading power in the world. Our friends and our adversaries respect us in large measure because they know that we are steady. We are fact-based. We are serious.

I have a range, and I'd much rather do things the nice way than the hard way, but sometimes you have to use all the tools at your disposal.

I spend every day up at the United Nations where I have to interact with 192 other countries. I know how well the United States is viewed.

I am straight forward; I am not manipulative; I am not two-faced. And I think that that has served me well in all of my roles, particularly as a diplomat, because people knew if I said something, I meant it. If I said no, I meant no, and if I said we could make this work, we would make it work.

It's in our interest to continue with the Paris Agreement and to deal with climate change as the real threat it actually is.

It is manifestly in the interest of the United States to deal with the very real threat that climate change poses. And that's why President Obama has worked so hard to reduce our own emissions and to lead internationally in forging the Paris climate agreement.

I think people have confidence that I will fairly and accurately represent their point of view to the President, and that I'm not going to put a spin on it, even if I may disagree with it.
